Either to check the time or waste time, people often look at their smartphones after waking in the middle of the night. While this acute burst of light does make it more difficult to fall back to sleep, a new study reports that it won't interfere with the body's overall circadian rhythms.

A bone cancer known as osteosarcoma is genetically similar in dogs and human children, according to the results of a new study. The findings could help break the logjam in the treatment of this deadly disease, which hasn't seen a significant medical breakthrough in nearly three decades.

A significant jump in preterm births to Latina mothers living in the U.S. occurred in the nine months following the November 8, 2016 election of President Donald Trump, according to a new study.

Infants born to women exposed to high levels of air pollution in the week before delivery are more likely to be admitted to a newborn intensive care unit (NICU), suggests a new analysis.

Offering children a wide variety and large quantities of snack food encourages them to eat more - and may contribute to weight problems, a new study has found. The research also found that how snacks are presented (in a large or small container) has little influence on how much children snack.

More than half of our genome consists of transposons, DNA sequences that are reminiscent of ancient, extinct viruses. Transposons are normally silenced by a process known as DNA methylation, but their activation can lead to serious diseases. Very little is known about transposons but researchers in an international collaboration project have now succeeded for the first time in studying what happens when DNA methylation is lost in human cells. These findings provide new insight into how changes in DNA methylation contribute to diseases.

A research team has analyzed for the first time the effect of the type of delivery on twins' psychological development and intelligence, demonstrating that cesarean section carries an independent risk in these multiple births.

Hearing loss has a profound impact on older people, as it can lead to anxiety, restricted activity, and perhaps even cognitive decline and dementia. Research has examined associations of hearing loss with outdoor activity limitations, psychological distress, and memory loss in people aged 65 and over. All three conditions were significantly worse when there was hearing loss. The findings support early interventions such as use of hearing aids.

Researchers have taken significant steps in understanding the way that the anti-malarial drug primaquine (PQ) works, which they hope will lead to the development of new, safer and more effective treatments for malaria.

3q29 deletion syndrome is a strong risk factor for both schizophrenia and autism spectrum disorder. People with the rare condition have a distinct neuropsychiatric profile, researchers found.

For years, surgeons have estimated how long a surgery will take. Now, researchers have created a model using data from more than 45k surgeries over four years.

Researchers have described a novel biochemical strategy used by bacteria to synthesize natural products.

Researchers have performed the largest GWAS study on type 2 diabetes in the sub-Saharan African populations, revealing an association between the disease and previously unlinked ZRANB3 gene. By using animal models, their results show that dysfunction of the ZRANB3 gene has major repercussions on insulin production. This link may hold key answers to the treatment of type 2 diabetes in all populations.

Up to two hours of endurance and resistance exercises daily during a long space flight mission, combined with IV fluid replacement after landing, helps astronauts prevent dizziness and fainting during normal activity when they return to Earth. The study findings also have implications for a variety of people with health conditions that cause them to faint when standing up, and people on bed rest for long periods.
